Lance Armstrong steps down as chairman of Livestrong

(CNN) – Lance Armstrong is stepping down as chairman of the Livestrong cancer charity he founded in 1997 after recovering from the disease, a spokeswoman for the organization confirmed.

The move comes a week after the U.S. Anti-Doping Agency said it had uncovered overwhelming evidence of Armstrong’s involvement in a sophisticated doping program while a professional cyclist.

In addition, Nike has ended its contract with Armstrong.

“Due to the seemingly insurmountable evidence that Lance Armstrong participated in doping and misled Nike for more than a decade, it is with great sadness that we have terminated our contract with him,” the company said in a statement Wednesday. “Nike does not condone the use of illegal performance enhancing drugs in any manner.”
